Hmmm... Well, when I print the little 25mm hollow cube, it comes out 24.75mm on a side (every side), so it's definitely X/Y/Z scaling, and I've noticed the same scaling factor on a variety of other parts I've designed. It's very consistent... Granted, it's less than 1% off, but when I'm design press ...

Thanks, I'll give that a go. I'd say the bed is level with 0.002" or so. (i.e. no dial indicator, but it passes the "uniform-grab-on-a-sheet-of-paper" test nicely.) I assume I'll have to recalibrate the bed height after changing the arm length parameter?

I know this is an older thread, but I have a similar problem, my scale is off by a factor of 1.0098 in all dimensions. I've gotten used to simply adjusting the scale of the STLs in Repetier Host, but I'd prefer to fix this properly, using the firmware configuration; what parameters should I be ...

Ah, that's excellent, I hadn't come across anything that definitively stated whether the 0.9 firmware solved the problem. I have a couple jobs I need to slog through before I can get some down-time to swap the RAMBO, recal, etc., so I'll try nudging the layer thickness. Worst-case, I'll just splice ...

Hi all, I've been running the the V.0.83 firmware for some time on a Rostock MAX, with an E3D hot-end, without any trouble, but over the past couple days, the machine's been stopping, 60-90% of the way through the job. This has happened twice when streaming the job via USB (Repetier Host V0.95C ...
